Q1.)CALCULATE THE WORK DONE TO DISSOSIATE THE SYSTEM OF THREE CHARGES PLACED ON THE VERTICES OF THE TRIANGLE ABC
HERE q=1.6 * 10-10 C
all side of 10cm ,A=q ,B=2q,C=-4q
Work done in dissociate this charge configuration will be negative of the potential energy of the system.
Work done can be calculated using the above relation.
